Corn. Safer on my compression.

Oh that's right, you already told me that...

I'm curious to see if a single Wally will be enough to supply an 2.2L w/EF2.5...I definitely have my doubts. I honestly don't think my fuel setup (Walbro 255HP w/ID1k injectors) would support my car on E85 unless the tune was purposely held back.

Future plans still include a surge tank, so I don't want a big ass 450 in there. PLus the 450 was causing some pretty high idle pressures hardwired. And with 2150's and high base pressure that sucks for idle!

I just want to simplify everything and hopefully get some more "proven" shit in there. A 255 to me is very proven. I think with an AFPR and my 6AN feed line and 1300's I will be close for the 2.5 on corn. We will see. If not, I will just run with 450whp and keep it all safe. Then get the surge tank with wally 450 in it like I had planned.

I feel the same way.

Based on what I've experienced over the past 2 weeks with maxing out a single 255, I'd would agree.

If that is the case, maybe I will look at something else.

I was under the impression the wally 255 was good for 600whp or so (dynojet, not Shane DB dyno) on 93 and roughly 500whp e85.

Like I said I wouldn't mind stopping around 475whp or so if I need headroom. I could run higher base pressure too if need be as I am not planning to run 35psi or anything anyway.

I guess we will see.

Guess what power level I was at when I ran out of pump on E85

I just installed a Wally 400 E85 aka Walbro 416 aka Walbro 450 and fuel pressure issues have been resolved.
